Why would we be interested in this? What does it have to do with Raspberries?

Perhaps not much now a days. But bear with me:

The Raspi uses an ARM processor. That ARM processor has a linage going back to the first Acorn RISC Machine built by Acorn in the 1980's. Which, interstingly, was the fastest personal computer one could hope to buy at the time.

Ah yes, forgot about those. And it was only a while ago I was installing OpenWRT on such routers and compiling my own code to run on them with a MIPS GCC compiler. I remember thinking it was odd that MIPS dominated that market rather than ARM.
